Tìm \(\large x\), biết 14 × 6 × 2 + \(\large x\) + 213 = 559 \(\large

Tìm \(\large x\), biết 14 × 6 × 2 + \(\large x\) + 213 = 559

• A.

  \(\large x\) = 167

• B.

  \(\large x\) = 125

• C.

  \(\large x\) = 164

• D.

  \(\large x\) = 178

14 × 6 × 2 + (\(\large x\) + 213) = 559

84 × 2 + (\(\large x\) + 213) = 559

168 + (\(\large x\) + 213) = 559

\(\large x\) + 213    = 559 – 168

\(\large x\) + 213    = 391

 \(\large x\) = 391 – 213

\(\large x\) = 178

Vậy  \(\large x\) = 178
